This gland is responsible for producing and secreting thyroid hormone (thyroxine), which affects nearly all body systems. Thyroxine is the hormone that is primarily responsible for regulating the metabolic rate of many different tissues in the body. In hypothyroidism, not enough thyroxine is produced, which causes the metabolism of these tissues to slow down. Hypothyroidism is the most common endocrine (hormonal) disorder in dogs and often develops between the ages of 4 to 10 years. It usually affects castrated male and spayed female dogs. A variety of dog breeds are afflicted with this condition, such as the golden retriever, Doberman pinscher, greyhound, Irish setter, dachshund, miniature schnauzer, Great Dane, poodle, and boxer. The disease also occurs in mix breed dogs and many other breeds. Hypothyroidism can be divided into primary and secondary causes. Most cases are primary, which means that there is destruction of the thyroid gland from inflammation, degeneration, or infiltration with tumor. Inflammation of the thyroid gland is thought to be caused by the dog's own immune system. Secondary hypothyroidism develops when some other influence causes the thyroid gland to produce less thyroxine. Examples include diseases of the areas of the brain that regulate thyroid gland activity, destruction of the thyroid gland from radiation therapy, surgical removal of the thyroid glands, or the administration of certain medications that affect thyroid gland activity. What To Watch For A deficiency of thyroid hormone affects the metabolic function of many organ systems. As a result, the clinical signs are usually variable, non-specific, and slow to develop. Although there is no one symptom that is diagnostic, several combined signs may make your veterinarian more suspicious. Symptoms may include: Lethargy, lack of interest in play, increased amounts of sleeping Depression, mental dullness Exercise intolerance (tires easily) Weight gain (without an apparent increase in appetite) and obesity Cold intolerance – seeks out warm places to lie down, low body temperature Slow heart rate (bradycardia) Infertility Constipation Diarrhea Chronic skin disorders, such as dry skin, thinning of the hair coat, excessive hair loss Possibly other neurologic signs Possibly other hormonal abnormalities / : ` s š Ђ   Ё Ђ јюјхјлјхјЮB*CJOJQJaJph5B*\aJph0JB*aJph6B*]aJph B*aJph јљuvЗИ` r s А Б ь [ { Ђ §§§§§§§§§§§§§§§Ђ ў 1hАа/ Ар=!Аа"Аа#а$а%А i8@ёџ8 NormalCJ_HaJmH sH tH <A@ђџЁ< Default Paragraph FontўoЂё klink&ўoЂ& preloadwrapЂ џџџџјљuvЗИ`rsАБь[ { Є ˜0€€˜0€€˜0€€˜0€€˜0€€˜0€€˜0€€˜0€€˜0€€˜0€€˜0€€˜0€€˜0€€˜0€€˜0€€Ђ Ђ Ђ „ŒеоІЏHQвнj t Є Є їЁ Є џџ ASHRAF GOMAAIC:\Documents and Settings\MOHSEN GOMAA\Desktop\Abbott Web\hypoT4 dogs.docџ@€qq ˆDŠŠqqЂ P@џџUnknownџџџџџџџџџџџџG‡z €џTimes New Roman5€Symbol3& ‡z €џArial7& ‡ ŸVerdana"qˆ№аhяСщІєСщІdё!№ааxД‚‚r0Р 2ƒQ№џџ~Hypothyroidism is a disorder of the thyroid gland, which is the butterfly-shaped glandular organ located in the neck just belo ASHRAF GOMAA ASHRAF GOMAAўџр…ŸђљOhЋ‘+'Гй0№˜ ,DP\l „ Ќ И ФаиршфHypothyroidism is a disorder of the thyroid gland, which is the butterfly-shaped glandular organ located in the neck just beloypo ASHRAF GOMAAm iSHRSHRNormalG ASHRAF GOMAAm i1HRMicrosoft Word 9.0 @^аВ@в™2о[Ы@0jхо[ЫdёўџеЭеœ.“—+,љЎ0h hp|„Œ” œЄЌД М Gф hР   Hypothyroidism is a disorder of the thyroid gland, which is the butterfly-shaped glandular organ located in the neck just belo Title ўџџџўџџџўџџџ!"#$%&'ўџџџ§џџџ*ўџџџўџџџўџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџRoot Entryџџџџџџџџ РF+юьо[Ы,€1TableџџџџџџџџџџџџWordDocumentџџџџџџџџ"SummaryInformation(џџџџDocumentSummaryInformation8џџџџџџџџџџџџ CompObjџџџџjObjectPoolџџџџџџџџџџџџ+юьо[Ы+юьо[Ыџџџџџџџџџџџџўџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџџўџ џџџџ РFMicrosoft Word Document MSWordDocWord.Document.8є9Вq
